Write the electron configuration of a -2 ion with 16 protons.
Answer:
1s^2 2s^2 2p^6 3s^2 3p^6
Explanation:
Number of electrons = Number of protons. Originally, sulfur has 16 protons, but the question asks states 2- ions. So S^(2-), or a total of 18 protons. Follow the rules, and make sure the exponents add up to 18. 2 + 2 + 6 + 2 + 6 = 18 electrons.

Liquid B has a mass of 75 g and a volume of 25 ml. What is liquid B's density?
1: .33 g/ml
2: 3 g/ml
3: 75 g
4: 25 ml
Answer:
To measure the density of a liquid you do the same thing you would for a solid. Mass the fluid, find its volume, and divide mass by volume. To mass the fluid, weigh it in a container, pour it out, weigh the empty container, and subtract the mass of the empty container from the full container.
Explanation:
Answer:
[tex] \rho = \frac{mass}{vol} \\ = \frac{75 \: g}{25 \: ml} = 3g .{ml}^{ - 1} [/tex]

Kinetic energy → the kinetic energy of an object is the energy that it possesses due to its motion
For an example ↓
In 1988, three gray whales were trapped in Arctic ice. Television crews captured the frantic attempts of hundreds of people to save the whales. Eventually, a Soviet icebreaker and U.S. National Guard helicopters arrived to help free the whales. The cost of the rescue mission exceeded $5 million.
i. Write a scientific question related to the whale story.
ii. Write a nonscientific question related to the whale story.
The scientific question related to the whale story is how were the whale's rescued? The non-scientific question related to the whale story is what was the need for spending such large amount of money?
What is a scientific question?It is a one where an investigation can be designed and can be approached to completion in order to find out an answer.This can be done without doing different investigations.
It should have valuable information and should have the potential that it can be answered by direct observations.It should always lead to a hypothesis.
A scientific question must have the following characteristics:
It must have an objective and should be testable.It should focus on an independent variable and a dependent variable.It should be feasible and coherent.Whereas, characteristics of a non -scientific question is that they are broad,and have many variables to be tested.

What is the answer with the proper significant figures 7.6+2.401+0.68=
Answer:
10.7
Explanation:
The addition of 7.6 + 2.401 + 0.68 = is 10.681.
According to the addition of sig figs, you want your answer to have the same amount of places, after the decimal point, as the least sig-fig figure.
7.6
2.401
0.68
+
----------
10.681 - Draw a line straight down from the least sig-fig figure (7.6)
So the maximum figure after the decimal point is one. Since 8 is greater than 5, you have to round up from 10.6 to 10.7.

A reaction occurs that results in a molecule with two atoms of the same element. The atoms share six electrons. Which molecule could be the product of the reaction?
Si2
N2
O2
F2
Answer:
n2 is correct
Explanation:
i took it just now. :)
The product of this reaction could be N2.
Among the options, only atoms of nitrogen have five electrons on their outermost shell.
The fact that they have five electrons in their outermost shells implies that they can combine by sharing six electrons in a triple bond.
When this occurs, each of the nitrogen atoms involved in the bond now has an octet of electrons. Hence, the product formed when the atoms share six electrons. Which molecule could be the product of the reaction is N2.

Which idea was not supported by Dalton's atomic model but was supported in
all later atomic models?
A. A central, positive nucleus
B. Electrons in orbits
C. Positive and negative parts
D. Electron clouds
Answer:
It’s A
The indivisibility of an atom was proved wrong: an atom can be further subdivided into protons, neutrons and electrons. However an atom is the smallest particle that takes part in chemical reactions. According to Dalton, the atoms of same element are similar in all respects.
Which electron transition would result in the emission
of energy?
A) 3s to 4s
B) 3p to 4p
C) 3s to 3p
D) 4p to 4s
HELP PLEASE!!
Answer:
When the electron transits from an excited state to its lower energy state, it will gice off the same amound of energy needed to raise to that level. This emitted energy is a photon.
The answer is C, 3s to 3p.

2 H2O(l) → 2 H2 (g) + O2 (g) ΔH°rxn = +572 kJ Determine the heat associated with the reaction (qrxn, in kJ) when 4.85 grams of H2(g) is produced.
The heat associated with the reaction (qrxn, in KJ) when 4.85 grams of H₂ is produced is +693.55 KJ
Balanced equation2H₂O → 2H₂ + O₂ ΔH°rxn = +572 KJ
Molar mass of H₂ = 2 × 1 = 2 g/mol
Mass of H₂ from the balanced equation = 2 × 2 = 4 g
SUMMARY
From the balanced equation above,
When 4 g of H₂ is produced, 572 KJ of heat where needed.
How to determine the heat requiredFrom the balanced equation above,
When 4 g of H₂ is produced, 572 KJ of heat where needed.
Therefore,
When 4.85 g of H₂ is produced = (4.85 × 572) / 4 = +693.55 KJ of heat will be required.
Thus, +693.55 KJ of heat is required for the reaction.
